Keyword Extractor

Keyword Extractor reads a block of text, or a page's HTML, and returns the terms that actually characterise it: single words and multi-word phrases, ranked, with the filler removed.

Ranking by raw frequency alone produces a useless list, because the commonest words in any English text are the same ones every time. Two things fix that here. Stop words are removed, so 'the' and 'and' never appear. More importantly, phrases are scored by a weighting that rewards terms appearing often across the whole text rather than clustered in one paragraph, which is what separates a genuine topic from an aside.

Multi-word phrases are where the value is. 'Keyword' tells you little; 'keyword density checker' tells you what the page is about and is the kind of phrase people actually search. The tool extracts two, three and four-word phrases alongside single terms and ranks them together.

HTML is handled as well as plain text. Paste a page's source and script, style and navigation content is stripped before analysis, so the result reflects the readable content rather than the markup.

Nothing you paste leaves your browser. There is no upload, no log and no account, which makes it safe to analyse a staging site or an unpublished draft.

The keyword extractor is used by writers, developers, students, marketers and anyone else who needs the job done once without installing software. Common cases include:

• Working out what a competitor's page is actually targeting
• Checking that your own page is about what you intended
• Finding phrase ideas from a long document
• Summarising a research paper or report into its topics
• Building a tag list from an article
